A second c lin- 106 tion of the trimming protecting device or der 17, having one o en and one cosed shield when the' latter is employed. Figure end and external threa s adjacent said open I 2 is a vertical longitudinal section of the apend, is formed of rust resisting material and "paratus shown in Figure 1, a portion only with a diameter greater than that of thel of the supporting standard being shown. cylinder 16 and is adapted for engagement 0 with threads formed internally of the bore 13 adjacent the .open end thereof, whereby the cylinder 1,7. is supported byv and -laterally of the elbow in concentric relation with and spacedfrom the cylinder 16. A steam line 18 leads from any suitable source of steam such as a boiler (not shown) to and through the end closure of the cylinder 10 and an extension of said line, 19, extends longitudinally within the cylinder 16 to a point adjacent the closed end thereof, where it terminates in an open end. A return pipe or vline 20 is likewise tapped through the end closure of the cylinder 10 and communicates with the chamber within the cylinder 16 at its lowermost point, leading from thence to .theboiler or source of steam. Cut-off valves or other control means may be installed in the llines 18 and 20 when and as desired, but such valves are not to be` employed in theoperationof the a paratus, it being desirable that steam sha1 at all times be led through the pipe 18 and extension 19 into the chamber Within the cylinder 16, circulated within4 said chamber and, i together with thejwater of condensation that may form,:.returi`ied to the boiler by means' of the .pipe 2O. Thus is provision made for establishing and maintaining, automatically, a .high temperature within the apparatus to the. endcvthat all operating parts of the apparatus may be heated and so that operat ing steam admitted to the-a paratus will not be subjected to coolin an condensation through contactI with co d metallic parts. A branch 21,-diverges from the steam line 18 and leads through a control valve 22 to a (passage 23 communicating through the en .closure ofl the cylinder 10 with that rtion of the bore 13 surroundin the cylinder 16. The valve 22 is norma ly closed cylinder. may drain to the el ow andV be trapped within the chamber formed by the bore 12 and closed end of the standard 14, from whence a drain pipe 26 leads through a trap.4 27 to a receptacle,sewer connection or the like. The trap` 27 may be of any desiredstyle, a simple conventional form consisting of a recurved pipe being shown, it being the function .ofv said trap to prevent easy escape of the steam within the cylinder 17 and compel said steam to circulate within said cylinder and through the perforations 25. Y

The modifications illustrated in Figures 4v 5 and 6 are purely matters of structure and form, the principles of operation being in all respects the same as above setv forth. In the latter views, the cylinders 16 and -17 are shown tapered in width and thickness, whereby a greater range of usefulness of the apparatus may be had. The cylinder 17 is shown with an annular flange 17 about its open end in place of the threads above described, said flange being vadapted to be clamped to the open end of the cylinder 10 by means of a collar 28 and cap screws 29 a gasket 30 being interposed between sai flange and the end of the cylinder 10 to prevent leakage of steam. It is of course apparent that this latter method of connecting the cylinders 10 and 17 may readily be substituted for the threaded relation in the form shown in Figures 1 and 2. In Figures 4, 5 and6 the cylinder 1l is shown with a closed outer end provided with an annular flange 11 adapted to be bolted to a corresponding flange 14`formed on ythe upper l end of a standard 14', said standard being illustrated as having a cruciform cross section. These 'modifications .are but variations of the .construction hereinbefore described and are adaptable to the form of.

apparatus shown in Figuresl and 2.

Insomuch as garment trimming, such as fur and the like, maybe damaged through contact with steam and heat, a protecting.

shield adapted to slip over the cylinder 17 and insulate portions of the garment'from said cylinder, is provided. As shown in vFigure 7, such a shield may consist of a sheet of fiber'or similar material, 31, to one surface of .which is secured by shellac or glue and stitching a sheet of felt or similar thus formed being rolled to form a cylinder of suitable diameter with the absorbent material on the inside, the edges of the sheet being overlapped and secured by rivets'33 or other fastening means. When the shield as above described is in use on the apparatus, the absorbent material serves yto insulate the fiber 31 from the heat of the steam and absorbs .the moisture therefrom, so that porabsorbent material, 32, the composite sheet,

tions of the garment in contact with said closed outer end carried valve 22 and passage 2d to the chamber between the cylinders 16 and 17, from whence,

owing to the resistance of the trap 27, it is forced through the apertures 25 and the fabric thereover. lVater of condensation aud excess steam is exhausted from the cylinder 17 through the drain` 26 and trap 27 and water forming within the cylinder 16 is returned to the boiler with the steam through the pipe- 20, thus insuring that the steam emitted through the perforations 25 is at all times dry and of high temperature.

I claim as m invention- 1. A steam support, an elbow member carried by said support, spaced, parallel, concentric cylinders having closed outer ends carried by and projecting laterallv of said elbow, the outer of said cylinders icing perforated and the inner of said cylinders being imperforate and sealed from the outer cylinder, and means whereby steam may be circulated continuously within said inner cylinder and selectively within said outer cylinder.`
